What is the Origin of Estrogen Hormone Therapy?

The practice of hormone replacement therapy has historical roots dating back to the early 20th century, evolving significantly with the isolation and synthesis of stable steroid hormones. The specific term EHT arose as a clinical designation to distinguish estrogen-only treatment from combination hormone therapy. This nomenclature reflects the growing understanding of the need for concurrent progestogen in women with an intact uterus to prevent endometrial hyperplasia.

What is the Mechanism of Estrogen Hormone Therapy?

Administered estrogen exerts its therapeutic effect by binding to and activating nuclear estrogen receptors (ERα and ERβ) in various target tissues, including the bone, brain, and cardiovascular system. This ligand-receptor complex translocates to the nucleus, modulating gene transcription to restore normal cellular functions. The primary mechanism in symptom relief is the re-establishment of estrogen-mediated signaling pathways that govern thermoregulation and tissue trophic effects.

Estrogen Hormone Therapy

Meaning

Estrogen Hormone Therapy (EHT) is a targeted clinical intervention involving the administration of exogenous estrogenic compounds to mitigate symptoms and address the physiological consequences associated with estrogen deficiency. This therapy is typically utilized in postmenopausal women or following surgical removal of the ovaries. EHT aims to restore circulating estrogen levels to a therapeutic range, alleviating vasomotor symptoms and preventing accelerated bone mineral density loss.
